STOP FOR WINDOW-BLINDS.

SPECIFICATION forming part of Letters Patent No. 687,796, dated December3, 1901.

Application filed March II 1901. $eria1No. 50.587. (No model.)

To all whom it may concern:

Be it known that I, THERON A. UPSON, a citizen ofthe United States,residing in the borough of Brooklyn, county of Kings, city and State ofNew York, have invented certain new and useful Improvements in Stops forWindow-Blinds, of which the following is a specification.

My invention aims to provide an improved stop for window-blinds which iseasily accessible, which is quickly set in position to hold the blindopen or released to allow the blind to close, which is simple inconstruc tion and therefore cheap to manufacture, which is not likely toget out of order, and which in one form. or another can be adapted tothe various methods of hanging windowblinds at present in existence.

My invention provides alsoa stop ofthe character specified which hasvarious other advantages, all of which will be enumerated in detail inthe specification hereinafter.

Referring to the accompanying drawings, which show several specificembodiments of myinvention, Figures 1, 2, and 3 are perspective views ofa form of my invention which is especially adapted for use in connectionwith one method of supporting the blind from the window-frame. Fig.4 isasection through the hinge member which is attached to the blind in Fig.3. Fig. 5 is a perspective view of a modification in which the stop ispermanently attached to the hub of the hinge shown in Figs. 1, 2, and 3.

The principal distinguishing feature of my invention is that it providesa stop which bears against the inner edge of the frame of the blind andwhich is firmly attached to the window-frame at a point adjacent to theedge of the blind when open. For the pur poses of my invention the faceof that portion of the hinge which is attached to the blind isequivalent to the inner edge of the blindframe-that is to say, theefiect is the same whether the stop bears against the inner edge of theblind-frame proper or against the corresponding face of the portion ofthe hinge whichis attached to the blind-frame and moves with it, asshown in Figs. 1 to 4:. It is obvious also that most of the forms whichmyimproved device admits of can be attached to the blindframe and bearagainst the inner edge of the window frame or that it may be attached tothe blind portion of the hinge and bear against the fixed portion of thehinge, since it is the relative movements of these several parts whichis to be prevented.

In Figs. 1 to 4 I show a form of my device specially adapted forattachment upon a particular style of hinge much used in hanging blinds.This type of hinge comprises relatively movable members A and B, ofwhich the former is usually attached to the window frame and thelatterto the blind-frame. The member A has usuallya hub A, Fig. 5, whichcarries the pin A upon which the blind member of the hinge turns. 0 is astop, shown in the present case as arranged to-bear against the innerface of the member 13 of the hinge and which is made laterallyadjustable to suit the different positions in which the member B lieswhen the blind is open, depending upon the mode of attachment of theblindframe to the member B and upon the position of the member B on thepin A Thus in Fig. l the member B is on the outer side of the pin A andthe blind-frame D is attached to the bent end B of the hinge member B.-In Fig. 2 the blind-frame D does not go back entirely parallel to thewall and is attached to the front of the hinge member B, which for thispurpose is flat. In Fig. 3 the blindframe D is attached to the bent endB of the hinge member; but such member is on the inner side of the pin AVarious other arrangements are possible; but it is evident that thecapability of lateral adjustment of the stop 0 provides for any casewhich may occur.

The particular form of stop 0 which I propose to use with such a hingeconsists of a screw-threaded rod 0, having heads 0 and c at oppositeends and passing through a nut E, which is fixed on the hub of themember A, as hereinafter described. To set my improved stop, it is onlynecessary to push the blind to its farthest opened position and thenscrew the stop up against the blind member 13 of the hinge. It is thenset for all time for this particular blind and requires only to beraised and lowered to hold the blind open or to permit it to shut.

Either the head 0 or the head 0 may be used as the bearing portion ofthe stop, the former being shown in Figs. 1 and 2 and the latter inFigs. 3 and 4.

To permit the closing of the blind, the stop is arranged to be lowered,and for this purpose I preferably arrange the nut E on avertically-adjustable slide F, which moves in a guide G, which isattached by means of a sleeve H to the hub of the fixed member A of thehinge. Any suitable means maybe provided for attaching the sleeve H tothe member A, such as one or more thumb-screws H or wedges, or any othermeans whatever for exerting a pressure between the hub of the member Aand the sleeve II. It will be understood also that any suitable meansmay be employed for attaching the guide G to the sleeve H, such asscrews, rivets, plugs, or the like. This guide G preferably consists ofa single piece of metal bent around the edges of the slide F, as shown.The upper bent portion fof the slide F prevents it from falling throughthe guide G, and the lower end of the slide F is also enlarged in anysuitable way, as by spreading it at the corners, as shown at f, toprevent its being accidentally pulled upward out of the guide G. Foradjusting the slide I provide, preferably, a setscrew K, which iscarried in either one of a plurality of holes f in the slide. In orderto hold the slide more firmly in position, I

' may provide also a plurality of depressions or holes 76, Fig. 5, inthe guide, into which the end of the screw K enters.

Where it is desired to make the stop a permanent part of the hinge, theguide G may be attached permanently to the hub A, as shown in Fig. 5,either by means of screws 70 or by means of plugs, rivets, or otherwise,as in attaching it to the sleeve H. In this figure I show also a spacerkiwhich may be found necessary to bring the slide a sufficient distanceaway from the pin.

It will be seen that my invention because of its simplicity and genericnature admit-s of a great number of embodiments differing widely fromeach other without necessarily departing from the essential principle ofthe invention. It will be understood, therefore, that my inventionincludes all modifications of the specific embodiments herein set forthwhich employ the same principles of construction and operation.

\Vhat I claim, therefore, and desire to secure by Letters Patent, arethe following-defined novel features, each substantially as described:

1. The combination with a blind-hinge having a hub A on one of itsmembers, of a stop, a sleeve connected to said stop, and means forattaching said sleeve to said hub.

2. The combination with a stop, of means for attaching the same to onemember of a blind-hinge, said stop being adapted to bear against theinner side of the other member, and means for adjusting the position ofsaid stop laterally to adapt it for differently-arranged hinges.

3. The combination with ablind-hinge having a hub A on one of itsmembers, of'a stop, means for attaching the same to said hub, said stopbeing adapted to bear against the inner side of the other member, andmeans for adjusting the position of said stop laterally to adapt it fordifferently arranged hinges.

4. The combination with a blind-hinge having a hub A on one of itsmembers, of a stop, a sleeve connected to said stop, means for attachingsaid sleeve to said hub, and means for adjusting the position of saidstop laterally to adapt it for differently arranged hinges.

5. The combination with a stop, of a vertically-moving slide carryingsaid stop, a guide for said slide, and means for attaching said guide toone member of a blind-hinge.

6. The combination with a stop, of a vertically-moving slide carryingsaid stop, a guide for said slide, and means for attaching said guide toone member of a blind-hinge, said stop being adjustable laterally insaid slide.

7. The combination with a stop, of a vertically-moving slide carryingsaid stop, a guide for said slide, a sleeve connected to said guide, andmeans for attaching said sleeve to the hub of one member of ablind-hinge.

8. The combination with a stop, of a vertically-moving slide carryingsaid stop, a guide for saidslide, means for setting said slide at twodetermined points 75 on said guide, and means for attaching said guideto one member of a blind-hinge.

In Witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
